Supreme Court rules constitutional privacy protections apply to cellphone users location history

The Supreme Court ruled 6-3 that constitutional privacy protections apply to cellphone location data, using the case of bank robber Okello Chatrie, whose location was tracked via a geofence warrant. Justice Elena Kagan emphasized users retain privacy expectations even when sharing location data with services like Google, while Justice Samuel Alito dissented, arguing no privacy expectation exists for voluntarily shared data.
